TP2, Not using CDMA any more, flash to GSM

I don't know if it is ok or not for what I want to do. I currently have a Sprint Touch Pro 2, but I have no plan to use the CDMA network, so is there a GSM ROM I can flash to? Thanks.

Never flash a GSM specific anything to your CDMA device. To gain GSM access you'll need to HSPL unlock, SIM unlock then flash a new radio. Search or check the Rhodium CDMA stickies for more info and step by step instructions.

I have a Sprint TP2 (i live in London). I bought it just for the 3.5mm jack. The sprint CDMA phones (as far as I'm aware) are already GSM unlocked to make it easier for their customers to ROAM. Mine definitly was, I just inserted my Vodafone Sim Card and switched it GSM (All Settings/Phone) and hey presto it's all good.
But definitley do NOT flash a GSM ROM to this phone it may brick it. There are plenty of good CDMA ROMS about here and on PPCGeeks (which leans a little more to CDMA).
Cheers.

this is like the 4th thread about this from the op, hopefully it has sunk in that this can't be done.

Verizon Htc TP2 Unlocking to GSM?

I tried doing a search for this thread and couldn't find anything, so if it has been talked about already my mistake.
So, my question is, Can a Verizon HTC Touch Pro 2 be unlocked to U.S. GSM Carriers?
It is a global phone and has a GSM radio and a Sim card slot. The thing I don't know is if the GSM radio is the proper frequency, if it isn't can that be changed? And if it is possible, how do I it do it?
And finally, does it need to be Sim unlocked or will I just have to switch the radio from CDMA to GSM?
Thanks much, Any help is much Appreciated.

[Q] Droid Maxx: Not activated on Verizon, won't work

After several long calls with Verizon and help from Motorola insiders, I have been given to understand that:
1. Droid Maxx if not activated on Verizon, before leaving US, cannot be used on other carriers (say in Europe or Asia).
The reason is the SIM unlock cannot be done by the customer support since they won't see the device in their network if it is not activated first.
2. The activation cannot happen outside US, since Verizon does not have a network.
So bottom line is get the device activated before you import it from US.
Now, my Droid Maxx is locked to Verizon. I know the boot loader can be unlocked. Will this help me in flashing something that can get rid of the SIM lock that Verizon has in place.
My device is an employee edition so perhaps there was some extra protection added there by Verizon.
Please help.

I do not have a Maxx, but I'm replying because you PM'd me asking to take a look at this thread..
It has been my experience that Verizon's 4GLte phones are sim unlocked (on the GSM side) out of the box. I thought that was a condition of VZW's 700Mhz spectrum auction win? One potential issue is does the phone support the needed bands out of the box (think Bionic where a hack was needed to enable bands needed for T-mobile).
That being said, if your Maxx is truly SIM LOCKED, then unlocking the bootloader wont help you SIM unlock, nor will flashing a 3rd party Rom after unlocking the bootloader.
where are you located, and who is your carrier? Do they use CDMA for voice, or GSM? What happens when you put a non-VZW sim in the phone?

Thanks Mark.
The phone Droid Maxx does support these bands since there are others who are using the same phone on GSM networks in the country.
The networks in India are:
2G capabilities GSM 900, GSM 1800
3G capabilities UMTS 2100
4G capabilities LTE 2300 (this one won't work with the phone, plus my carrier does not have it either)
The CDMA is CDMA 2000 - but I have not been able to try with a CDMA SIM, but that one has a higher probability of working.
When I put a non-VZ SIM, and set to Global mode, it does not detect any signal and the search network does pretty much nothing. The automatic mode tries to connect but then throws an error saying "can't connect to this network at this time"
I am using a brand new nano SIM card (which now is back in my Moto Defy with an adapter.)
Earlier I had a normal SIM converted to a nano SIM and that one did not work, but after I put in APN manually, I was able to access data.
I tried another user's cut-nano SIM and that one worked for data out of the box (another GSM provider).

Ditto for me, but I am using DroidMini... I also have DroidMAXX which is working great (even unlocked its BL and rooted it)...
I am also from India... Using it in GSM networks... I may get one Nano CDMA SIM to test later and will report here for sure...
Thanks...

Well, we have interacted on Rimweb recently.
The radio on the Droid series is the same. The difference between the mini and the maxx in your case is that the mini has never been activated on VZ network and hence it is SIM locked. Whereas, the Maxx would have been purchased as a used item (perhaps just activated and then sold off?). So that takes care of the SIM unlock part.

Yesterday I spend around 60 minutes with global support, VZ.
I escalated the issue to the supervisor.
He checked and said that the IMEI is clean and not in any sort of negative list. So there is nothing else that they can do.
He also said, the phones are unlocked by default for global use.
Obviously they don't want to dig deeper into why three phones are not working on GSM in India.
I am now running out of avenues. Does anyone have some debugging tool which can log what is happening when the phone tries to log on to the network?

The current Droid Maxx that Verizon sells supports the following..
LTE Band 13/4 700/1700
EDGE/GSM: 850/900/1800/1900,
HSPA/UMTS: 850/900/1900/2100 (download speeds to 42.2 Mbps, upload speeds to 5.76 Mbps
From what you listed, the Maxx should get GSM/Edge/HSPA/UMTS coverage there. And of course, no LTE.
The CDMA side of the Verizon phones is still "locked" so I also would not expect CDMA to work. In other words, if your carrier NEEDS CDMA, stop trying.

I've been through this with some trying the Moto X in India, and I've been through it while trying my T-Mobile and ATT sim's in my Verizon Moto X.
From what you are describing, it sounds like your APN settings for your carrier on the phone are not set right.
Example... When I put my T-Mobile SIM into my Verizon Samsung Galaxy S4, I get "unknown sim" and bars, but no network connectivity. Nothing works. By going into the mobile network settings on the phone and adding an APN with the T-Mobile settings, features like calling, SMS, data, etc. start working. I have had occasions where I thought I had the APN right, as calls and data worked, but MMS only partially worked (would send but not receive). When I do have the settings right, everything works. Similar thing happens on my Moto X with T-Mobile SIM.

Unless you have an active account with Verizon, and are trying to use their service when traveling, Verizon wont help you. In other words, unless you are trying to get your Verizon phone, working on Verizon's Global Roaming service, on your currently active Verizon account, they wont help you.
Even if you are a Verizon customer who is just traveling and popped out your VZW SIM in favor of using a local prepay sim to save data/voice costs, once you pop that VZW SIM out, they wont assist.
But you have received confirmation of what I said.. the GSM side is unlocked.
The SIM you are trying to use is from a GSM India carrier? As long as they only use GSM (no CDMA required), your only hope will be working with them. Telling them your phone is SIM Unlocked and going from there. Or finding a local message board for the carrier, and hope people are discussing use of "3rd party" phones, and you might get some help there.
I really think it will come down to the APN settings for the GSM carrier not being correct on the Maxx.
I can't offer any more than that. Sorry.

I have now put in a CDMA SIM card, but run into another problem with that. I will activate that SIM on another phone and then pop it in the Maxx again and check. But CDMA should work fine as reported by other users.
But the problem is the GSM part, because that is what we need to get working.

That is bad on the part of Verizon. I have purchased a Verizon device off-contract and that device is a global one. So I am entitled to some support from them even if I am without a service plan.

Yes. Local carrier. And for now, there are three such XDA members who have been facing the same issue. In one case, a member was able to make calls and receive calls and also use data. Then after a few minutes, the SIM invalid message popped up.

APN settings are pretty easy. I did that with my earlier SIM and I got data working. There was no voice, so I gave that SIM back to the carrier and got a brand new nano SIM. Now, nothing works. The old and new SIM are for the same number and same service provider.

Right, you got just DATA working with the APN settings, but the correct APN settings are also needed for SMS, MMS, Phone calls, etc.
I've had an issue where I had voice but no data, and it was related to APN. I've had an issue where I had voice, SMS, data but no MMS, again, it was related to APN settings for the carrier you are using.
So good luck!

the problem we sorted out to get gsm working in india first the phone must be activated on usa to get it work on india so can anyone help us > @s_u_n

So, after using the phone for a week on GSM with all application updates installed, I can safely state that
1. Verizon activation is not needed for non-VZ networks to work (at least outside US).
2. A full FXZ was installed and it probably solved the modem configuration mess that the phone might have been. Perhaps it unlocked something?
3. Four corner activation bypass method was used (as described in earlier Motorola phones).
Either 2 or 3 solved the problem
There was nothing to do with APN. Data works even without any APN settings out here, just like on my Motorola Defy.

Is there a SIM unlock for the XT1548 (CDMA) model?

My ultimate plan is to get a phone that I can use with both Ringplus and T-Mobile. I know about the Nexus phones and the new Moto X Pure, but I'm on a budget and the new Moto G is just what I want in features for the price.
So my first question is if I can get the XT1548 to work on Ringplus. But that question becomes mute if I can't even get it to work on Tmobile. On the plus side, if I can get it to work on Tmobile, the XT1548 supports LTE band 12. :good:
does anyone know if the XT1548 can be sim unlocked?

You need GSM.
I use an XT1540 on wind and that uses the same bands as T-Mobile I believe. ( I live in Canada. ) I've had previous phones on Wind Mobile that had T-Mobile tags so I believe they also use the UMTS (maybe 1700 band?) signal as well.
"Differences between unlocked GSM andCDMA*phones. This topic is important when it comes to*unlocking*a GSM or*CDMA*phone because they don't both work in the same way. It is because of the differences between them in regards to the hardware they use to connect to a network (SIM card versus no SIM card)." - http://support.mobileunlocked.com/h...ferences-between-unlocked-GSM-and-CDMA-phones - pulled from google for a bit of piece of mind.
Ringplus may have no sim (in order to keep you locked into their network.)
T-Mobile does include sim cards because I've pulled one out of said wind mobile phones lol

Thanks for your reply. maybe a little more context can help.
So, this is the thread that inspired my question.
http://forum.xda-developers.com/moto-x/general/guide-success-sim-unlock-sprint-xt1056-t2825155
RingPlus is a MVNO for Sprint. You can use a number of Sprint, Virgin, Boost phones on RingPlus. People have also gotten the new Moto X and the Nexus phones that work with all carriers working on RingPlus and T-Mobile at the same time by just switching sim cards. I want to do the same with the Moto G.
Because RingPlus is a MVNO of Sprint, it uses CDMA. This is why I would need to use the XT1548 instead of the XT1540. I hope that clears things up.

Ahhh okay! Yeah it does my bad heh I did kinda rush that answer. I would imagine as long as that variant supports both radio bands I would imagine it would work. I have a single sim but I have heard there is dual sim as well, that would probably be your best bet. Just check what frequency the carriers both run on and give your device model a scan on gsm arena or any spec observant website to see if it supports both.
Example : UMTS 1700 is the band I need in order to use wind mobile on phones.

First, if you are able to purchase an XT1548 you better be sure that it isn't subsidized and the service you purchase it from is willing to allow you to take that device to another MVNO. It's a matter of reaching a staff person who is able and willing. Ting may be the only one that will be helpful with this.
Second, good luck getting Sprint or someone to domestically unlock GSM for this phone. As of today, I doubt it will be easy. It may require you to activate the phone on Sprint service and then find the support chain that will domestically unlock GSM. They are not obligated to do this.
The jumping of hoops might look something like this:
1. Purchase unsubsidized XT1548 from Ting when it's available (PM me for $25 Ting referral credit).
2. Activate on Ting ($6).
3. Ask Ting to "release" the phone to be activated on Sprint.
4. Activate on Sprint.
5. Request DSU from Sprint.
6. Ask Sprint to "release" the phone to be activated on RingPlus.
7. Activate on RingPlus.
8. Activate T-Mobile SIM and install the SIM to see if the phone works on GSM (not 4G LTE capable).
EDIT: If you want to port your number, I wouldn't bother til your final activation.
Good luck!

The US Cellular version of the Moto E is apparently SIM unlocked. By US Cellular's device policy, none of their Motorola branded phones are SIM locked. Perhaps the US Cellular Moto G would be more likely to work on domestic GSM as well as Sprint MNVOs. Certainly that's true of the Moto E.

unlocking GSM on moto xt1548
I have a moto g xt1548 that I asked a friend to get me since I lost my prior phone. However i live in ethiopia for work and this phone doesn't seem to be connecting to the gsm networks here. I'm aware the phone was originally bought for use on virgin mobile's network, but I expected the gsm would work nonetheless here (I reckon the phone uses both CDMA and GSM bandwidths). Some help would be nice here. How can I get the phone to recognise the networks here. I have tried everything from GSM to WCDMA but yet to try LTE (which is also available in ethiopia). I need to get the LTE sim card first. Is there a way to do this? Otherwise would rooting and flashing a custom ROM help? Or is it possible to find a work around to unlock GSM connectivity otlf that is what is locked.?

x1548 is CDMA only as far as I'm aware.

No, the XT1548 supports:
XT1548 US (Sprint, US Cellular, Virgin Mobile)
CDMA: 800, 850, 1900
GSM: 850, 900, 1800, 1900
UMTS/HSPA: 850, 1700, 1900
LTE: B2 (1900), B4 (1700), B5 (850), B12 (700), B17 (700), B25 (1900), B26 (850), LTE-TDD: B41 (2500)
Single SIM
https://en.wikipedia.org/wiki/Moto_G_(3rd_generation)
This device should work in Ethiopia, at least as a basic GSM device, data above basic Edge service may not work.
According to GSM Arena, in that country 900Mhz is used for GSM, and 2100 Mhz for 3G, and 4G/LTE is not available. So the phone should work, but data service will not.

Virgin Mobile XT1548 Unlock
I have the Virgin Mobile XT1548 (on sale at Best Buy for $50 right now) and I'm trying to unlock it to work on T-Mobile. Has anyone managed to do this?
When I put a T-Mobile SIM card into the XT1548 no unlock window comes up, so I'm not holding my breath but it would be fantastic if anyone has found a way to unlock the Virgin Mobile version of the XT1548.

After a reboot, it does say "SIM card error" as a notification. If you click on that it takes you to a screen where it asks you to make sure the SIM card is inserted correctly and contact the service provider. Again nowhere to enter an unlock code.
SIM status in settings says: "Not available" for every field. I've tried all four different ways to insert the SIM card (in case I had it in wrong somehow) and still no luck.

That's okay, I'm just hoping someone out there has an unlock and is willing to share it or offer it for sale. For $50 this phone is a STEAL if you could SIM unlock it. I'm partial to its IPX7 waterproof capability as well.

I already unlocked the bootloader and I have CM13 already installed. I put an AT&T sim card when starting but I wasn't prompted for an unlock code. I did request an unlock code from www.doctorsim.com if that would even make a difference. I'm still waiting for it to be processed.

S6 Edge - G925R - US Cellular

I have a rooted S6 edge unlocked for US Cellular (G925R). I see a lot of ROMs here on XDA but moslty for other variants .
Is there a way to safely flash a ROM belonging to different version for the version that I have ? Is there a workaround that can accommodate this ?

I assume the G925R has an unlocked bootloader, which is how you got root.
You should be able to modify the updater-script in a ROM to allow it to flash properly on a G925R (zerolteusc), I guess a ROM for the T-Mobile S6 Edge could be edited to work on a US Cellular.
Don't try it without confirmation from a more experienced member though. I'm just saying, editing the build prop will work, but T-Mobile is a GSM based carrier whereas US Cellular is CDMA, so not sure if the ROMs for the G925T will work on your phone.

Thanks, I will look further. Pardon me if I am asking a silly question but I see an option to choose the preferred network mode as LTE/CDMA or LTE/GSM. Also my device has a SIM card slot so is this device capable of both CDMA and GSM ?Currently I am using a Tmobile SIM in it and I have also tried an AT&T SIM, both worked as I could make calls. I am asking this as I am planning to use this phone outside US and if the device is CDMA only it will not be able to work on the networks outside.

No problem.
Pop in a SIM Card of your choice and you can use the phone on most GSM based carriers even abroad.
You mentioned that AT&T and T-Mobile were working, so you're all set.
Verizon, US Cellular and Sprint devices are CDMA but they have a SIM slot. So they will work with GSM carriers provided they are unlocked.
Oh, and about the network mode, select the right one depending on your network. If you're on a CDMA network, choose LTE/CDMA or if you're on a GSM carrier, choose LTE/GSM.
